Week & Period: Week 25, Period 5
Topic: Measurement
Sub-topic: Understanding Weight and Capacity
Learning Objectives
By the end of the lesson, students should be able to:
Describe what weight and capacity mean
Compare and estimate the weight and capacity of objects using local and standard units
Previous Knowledge
Students already know how to identify objects around them and can describe them using size and shape.
Instructional Materials
Mathematics textbook for Grade 2, local objects (stones, bags, bottles, cups, cans, water).
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Teacher shows two objects (e.g., a stone and a feather) and asks: “Which is heavier?” Learners predict answers. Teacher also shows two bottles of different sizes filled with water and asks: “Which holds more?”
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Weight is how heavy an object is. Capacity is how much space something can hold.
Local units of weight include stones, bags, tins, and cans. For example, we may say a bag of rice is heavier than a small stone.
Local units of capacity include cups, bottles, and cans. For example, one bottle of water can fill two cups.
Standard units of weight are grams (g) and kilograms (kg). For example, 1000 g = 1 kg. Standard units of capacity are liters (l) and milliliters (ml). For example, 1000 ml = 1 l.
Examples:
- If one mango is heavier than one orange, then the mango has more weight.
- A bucket can hold more water than a cup; therefore, the bucket has more capacity.
Learners’ Activities (Expanded):
Learners lift and compare classroom objects to tell which is heavier or lighter.
Learners pour water into cups and bottles to compare capacity.
Learners discuss daily life examples: which holds more, a cooking pot or a spoon?
Assessment Checks:
What is weight?
What is capacity?
Give one local unit of weight and one of capacity.
Notes (Expanded & Detailed):
Weight measures heaviness while capacity measures how much something can hold. Local units are commonly used at home and in the market, but standard units help everyone measure equally and accurately.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Weight tells us how heavy something is, and capacity tells us how much it can hold. Local units are used in homes and markets, while standard units are used in schools, shops, and science.
Evaluation Method (Expanded):
Exit slip/quiz: Teacher asks learners to write down one object heavier than their book and one object that has more capacity than a bottle. Teacher will collect slips and provide oral feedback.
Assignment (Expanded):
At home, compare two items and write down which is heavier and which has more capacity.
Follow-up Activity:
Learners bring local items (cups, stones, tins) to the next class for practice.
Differentiation / Inclusive Strategies
Learners who struggle will use hands-on demonstrations. Fast learners will be given extra word problems comparing more than two objects.
